AD7656BSTZ-1

The AD7656BSTZ-1 is a high-performance, 6-channel, simultaneous sampling, bipolar analog-to-digital converter (ADC) designed for applications requiring high speed and precision. This device is part of the AD7656 family, which features reduced decoupling requirements and software compatibility with earlier versions of the AD7656/AD7657/AD7658 series.

Key features of the AD7656BSTZ-1 include:

1. Six Independent ADCs: The AD7656BSTZ-1 contains six independent, 16-bit (or configurable as 14-bit or 12-bit) ADCs in a single package, allowing for simultaneous sampling of six analog signals.
2. Bipolar Input Range: The ADCs support true bipolar analog inputs, with pin- or software-selectable ranges of ±10 V or ±5 V. This provides flexibility in interfacing with various analog signals.
3. High Speed Sampling: With a throughput rate of up to 250 kSPS (thousand samples per second), the AD7656BSTZ-1 is capable of handling high-frequency signals with minimal distortion.
4. Low Power Consumption: The device operates efficiently, consuming only 140 mW at 250 kSPS with a 5 V supply. This makes it suitable for applications where power consumption is a concern.
5. High Noise Performance: The AD7656BSTZ-1 offers high noise performance with a wide bandwidth and a signal-to-noise ratio (SNR) of 88 dB at a 10 kHz input frequency.
6. Flexible Interface Options: The ADC provides high-speed parallel, serial, and daisy-chain interface modes for easy interfacing with microprocessors, DSPs, or other digital systems. The serial interface is compatible with SPI, QSPI, MICROWIRE, and DSP protocols.
7. Industrial CMOS Process: Fabricated on the iCMOS process (industrial CMOS), the AD7656BSTZ-1 combines high performance with low power consumption in a robust package.
8. Package and Temperature Range: The device is packaged in a 64-lead thin quad flat package (LQFP) and operates over a temperature range of -40°C to 85°C, making it suitable for various industrial and commercial applications.

Applications for the AD7656BSTZ-1 include data acquisition systems, multiaxis positioning systems, industrial automation, and any other applications requiring high-precision, simultaneous sampling of multiple analog signals. Its combination of high speed, low power consumption, and flexible interface options makes it an ideal choice for these demanding applications.
